Description
技术领域
本发明属于耐火材料生产技术领域，具体涉及一种无水泥浇注料。
背景技术
耐火浇注料在制备过程中需要加入水泥作为重要的功能组分，以此获得足够高的常温强度，但是含有水泥的浇注料在中温时强度显著降低，高温时强度和抗侵蚀性下降。因此，含水泥的可塑料无法适应中高温阶段的使用要求。而简单的去掉水泥组分，则会令浇注料在使用时凝结速度变慢且无法获得有效的基础强度和硬度。
鉴于此，申请人设计了一种无水泥浇注料，在不添加水泥的前提下，也能够有效提升可塑料在中高温的使用强度、硬度以及耐磨性。
发明内容
本发明所要解决的技术问题是提供一种无水泥浇注料，能够有效提升可塑料在中高温的使用强度和硬度。本发明解决的第二个技术问题是通过科学设计施工步骤，令可塑料有效组分发生陶瓷结合反应，提升可塑料施工面的耐磨性。
为解决上述技术问题，本发明的技术方案是：提供一种无水泥浇注料，其特征在于包括如下步骤：
a.备料：按照如下质量份数备料并进行称重：
铝矾土 50-70份；
α-氧化铝粉末 10-15份；
刚玉骨料 20-30份；
硼酐 2-5份；
活性硅微粉 10-25份；
膨润土 10-25份；
氧化钛 10-20份；
硬化剂 5-10份；
减水剂 3-5份；
水 15-25份；
b.将铝矾土进行破碎后研磨成细粉，然后通过酸洗法初步除铁，得到处理后的铝矾土；
c.破碎：将刚玉骨料中加入硼酐并进行破碎和研磨；
d.混合输出：将所有物料充分混合得到最终成品，并将成品通过成料输送带输出进行包装即可。
优选的，所述硬化剂为氧化硅溶胶和氧化镁，其中氧化硅溶胶和氧化镁的质量比为1:1。
优选的，所述减水剂为三聚氰胺。
本发明所述的一种无水泥浇注料的施工方法，其特征在于将浇注料通过喷涂设备喷涂在施工面上，对施工面进行加热烧结，烧结温度450-550℃，保温2-3个小时，而后自然冷却至室温即可。
与现有技术相比，本发明的有益效果是：
本发明所述的一种无水泥浇注料，未使用水泥作为功能性组分，而是使用将刚玉骨料中预混硼酐的形式，施工采用烧结法，施工面从室温升至450-550℃，硼酐生成粘性液相，随后与α-氧化铝发生固液反应，生成更高熔融温度的化合物后将刚玉骨料固结在一起，由于陶瓷结合的反应能够有效提升可塑料在中高温的使用强度和硬度，提升可塑料施工面的耐磨性。
